Patricia O'Toole, author of "When Trumpets Call"

The last decade of Theodore Roosevelt's life was marked with controversy. He was strongly critical of the Wilson administration and had launched a challenge within his own Republican party that effectively divided that party. Additionally, he lost his youngest son in the First World War and suffered further reverses in his personal life as well. Patty O'Toole charts the last decade of a man who was so enamored of power that he was never able to fully surrender it.
